  abstract = {The most common platform for biogas process modelling, ADM-1, was extended adding the bio-electrochemical active CO2 reduction to CH4 reaction. The Nernst expression was incorporated as Monod-type kinetic expression to formulate the reaction rate, which is controlled by the electrical potential. The proposed model is applied to a complete mixed separate cathode compartment running in a continuous flow mode of operation. The model modification is relatively simple, mainly as a learning tool focused on the differences between an AD process with and without a Bioelectrochemical system (BES). The simulations demonstrate the basic concepts of BES for biogas upgrade and its limitations. The simulations show that biogas methane content can be increased up to 85 \% under the reactor settings selected for the simulations. The rate of the reduction reaction can be constrained by the local potential of the cathode and the substrate concentration. The necessity of maintaining some buffering from CO2 partial pressure to prevent the inhibition due to rise in pH is also pointed out. The simulations suggest that simultaneous bio methanation of CO2 from endogenous and external sources can be achieved using an AD with BES.},
